OnePlus Pad 3 VS Xiaomi Pad 8

The most striking difference in this category comes down to size and weight. The OnePlus Pad 3 is a substantially larger device — 289.6 × 209.7 mm versus the Xiaomi Pad 8's 251.2 × 173.4 mm — giving it roughly 44% more volume (364.37 cm³ vs 252.64 cm³). That size gap translates directly into portability: the OnePlus Pad 3 weighs 675 g while the Xiaomi Pad 8 comes in at just 494 g, a difference of 181 g. In practice, that's the weight of a medium-sized apple held in your hand for hours — a real factor for users who read, browse, or stream while holding the device. The Xiaomi Pad 8 will feel noticeably less fatiguing in one-handed or extended use scenarios.

Where thickness is concerned, both tablets are remarkably slim and effectively tied — 6 mm for the OnePlus Pad 3 versus 5.8 mm for the Xiaomi Pad 8 — a 0.2 mm gap that is imperceptible in everyday handling. Neither device offers water resistance or an attachable keyboard, so those dimensions of design are a wash.

The one meaningful advantage the OnePlus Pad 3 reclaims is the included stylus — a accessory the Xiaomi Pad 8 does not bundle in the box. For note-taking, sketching, or document annotation, this is a tangible out-of-the-box value add. Overall though, if portability and lightweight handling are the priority, the Xiaomi Pad 8 holds the clear design edge; if a larger canvas and a bundled stylus matter more, the OnePlus Pad 3 makes a reasonable trade-off despite its added bulk.

Both tablets share the same LCD IPS panel technology and a 144Hz refresh rate, so motion smoothness during scrolling and gaming is equivalent. Where they diverge meaningfully is screen size and pixel density — and interestingly, these two factors pull in opposite directions. The OnePlus Pad 3 offers a larger 13.2″ canvas with a 3392 × 2400 resolution, while the Xiaomi Pad 8 uses a smaller 11.2″ panel at 3200 × 2136. Because the Xiaomi Pad 8 packs a similar pixel count into a tighter area, it achieves a noticeably sharper 344 ppi versus the OnePlus Pad 3's 315 ppi. At typical tablet viewing distances, this difference is subtle but perceptible — fine text and detailed imagery will appear marginally crisper on the Xiaomi Pad 8.

The durability and glare story splits the two devices clearly. The Xiaomi Pad 8 features branded damage-resistant glass, offering meaningful scratch and impact protection — something the OnePlus Pad 3 lacks entirely. The OnePlus Pad 3 counters with an anti-reflection coating, which reduces glare in bright or outdoor environments. Depending on use case, each coating addresses a different real-world concern: longevity vs. visibility in sunlight. The Xiaomi Pad 8 also sports a higher touch sampling rate of 240Hz (vs. 144Hz), which benefits stylus precision and fast-paced gaming responsiveness. For the OnePlus Pad 3, this matters more given it ships with a stylus — making the lower sampling rate a mild but notable irony.

On HDR support, both carry Dolby Vision, but the Xiaomi Pad 8 additionally supports HDR10, broadening compatibility with streaming content across more platforms. The OnePlus Pad 3 lacks HDR10, which is a minor but real limitation for media consumption. Taken together, this category is genuinely competitive: the OnePlus Pad 3 wins on screen real estate and outdoor usability, while the Xiaomi Pad 8 edges ahead on pixel sharpness, touch responsiveness, glass protection, and HDR versatility — giving it a slight overall display edge for users who prioritize quality and durability over raw screen size.

The chipset gap here is substantial and unambiguous. The OnePlus Pad 3 runs on the Snapdragon 8 Elite, Qualcomm's flagship 3nm processor, while the Xiaomi Pad 8 uses the Snapdragon 8s Gen 4, a mid-tier derivative built on a 4nm node. Benchmark results confirm the real-world performance delta: the OnePlus Pad 3 scores 10,059 (multi-core) and 3,234 (single-core) in Geekbench 6, versus the Xiaomi Pad 8's 6,833 and 2,041 respectively. That's roughly a 47% multi-core and 58% single-core advantage — differences large enough to be felt in demanding tasks like video editing, AI-accelerated workloads, and complex gaming. The OnePlus Pad 3 also pairs this with 16GB of RAM at a faster 5,300 MHz speed and 85.1 GB/s memory bandwidth, compared to the Xiaomi Pad 8's 12GB at 4,800 MHz and 76.8 GB/s. More RAM at higher speeds translates directly into smoother multitasking and better handling of memory-intensive applications.

Storage and expandability follow the same pattern — the OnePlus Pad 3 offers 512GB of internal storage, double the Xiaomi Pad 8's 256GB, and neither device supports a memory card slot. For users who store large media libraries or offline content, this difference is meaningful. On the GPU side, the Adreno 830 in the OnePlus Pad 3 outclasses the Adreno 825 in the Xiaomi Pad 8, despite the latter having a marginally higher GPU clock speed of 1,150 MHz vs. 1,100 MHz — clock speed alone doesn't determine GPU capability when the underlying architecture differs significantly. The OnePlus Pad 3 also supports two external displays simultaneously versus one on the Xiaomi Pad 8, a productivity-relevant distinction for power users.

One counterintuitive data point worth flagging: the Xiaomi Pad 8 carries a higher TDP of 12.5W versus the OnePlus Pad 3's 8.2W, meaning it draws more power under load despite delivering lower performance — a sign of the efficiency gains the newer 3nm process provides the OnePlus Pad 3. The Xiaomi Pad 8 does ship with Android 16 out of the box while the OnePlus Pad 3 launches on Android 15, a software edge that may matter for users wanting the latest OS features immediately. Overall though, the OnePlus Pad 3 holds a commanding performance advantage across CPU throughput, RAM capacity, storage, and efficiency — making it the clear choice for users who push their tablets hard.

Rarely does a camera comparison come down to a single feature, but that is precisely the situation here. Both tablets are equipped with an identical 13 MP main camera and 8 MP front camera, both cap video recording at 4K at 30fps, and both share the same feature set across autofocus, HDR mode, manual controls (ISO, white balance, focus, exposure), flash configuration, and video light. Neither device offers optical zoom, optical image stabilization, slow-motion recording, or Dolby Vision recording — the omissions are shared equally.

The sole differentiator across this entire spec group is that the Xiaomi Pad 8 supports in-camera panorama shooting, while the OnePlus Pad 3 does not. For most tablet users this is a minor convenience — panoramas are a niche capture mode — but it does represent a tangible, if modest, functional gap.

In practical terms, cameras are rarely a primary buying consideration for tablets, and this comparison reinforces why: both devices sit at comparable, utilitarian camera tiers. Given that the spec parity is near-total, the Xiaomi Pad 8 holds a marginal edge solely by virtue of its panorama capability, but this should carry very little weight in any purchasing decision. Users on either device can expect essentially the same camera experience day-to-day.

Audio hardware is largely a tie between these two tablets. Both feature stereo speakers and both drop the 3.5mm headphone jack, meaning wired headphone users will need an adapter or a USB-C alternative regardless of which device they choose. Neither supports LDAC or any aptX variant beyond what is noted below — so for most wireless listening scenarios, the two are functionally identical.

The one distinction worth flagging is that the OnePlus Pad 3 supports aptX HD, while the Xiaomi Pad 8 supports no high-resolution Bluetooth audio codec from the provided data. aptX HD enables wireless audio transmission at higher bit depths and sample rates than standard Bluetooth, which can result in audibly richer sound when paired with compatible headphones. That said, the benefit is only realized with aptX HD-compatible headphones — users without such hardware will notice no difference whatsoever.

For the majority of users streaming music or watching video through the built-in speakers or standard Bluetooth headphones, this category is effectively a draw. For audiophiles who own aptX HD-capable headphones, the OnePlus Pad 3 holds a narrow but real edge in wireless audio quality. Everyone else can treat audio as a non-factor in the decision between these two devices.

Battery capacity is where the OnePlus Pad 3 asserts another clear advantage. Its 12,140 mAh cell is nearly a third larger than the Xiaomi Pad 8's 9,200 mAh — a gap of just under 3,000 mAh. All else being equal, a larger battery directly translates to longer time between charges, whether that's additional hours of video playback, browsing, or productivity work. It's worth noting that the OnePlus Pad 3 also has a larger, higher-resolution display to power, so real-world endurance gains may be somewhat moderated compared to the raw capacity difference — but the headroom is still substantial.

Both tablets support fast charging and share the same fundamental battery architecture: sealed, non-removable, and rechargeable. Neither offers wireless charging, so that convenience feature is off the table for both users equally.

With no further charging speed data provided to differentiate the two, the verdict here rests squarely on capacity: the OnePlus Pad 3 holds a meaningful battery advantage. For users who frequently use their tablet away from an outlet — on long flights, during travel, or in extended work sessions — that extra capacity is a tangible, practical benefit.

Connectivity specs are nearly identical across these two tablets, which makes the one numerical outlier stand out sharply: the OnePlus Pad 3 supports a maximum Wi-Fi download speed of 10,000 Mbits/s, compared to the Xiaomi Pad 8's 4,200 Mbits/s — more than double the throughput ceiling. Both devices support Wi-Fi 7 (802.11be) and share the same upload speed cap of 3,500 Mbits/s, so the gap is specific to download performance. In practice, this matters most in environments with a Wi-Fi 7 router and high-bandwidth tasks like downloading large files, streaming 4K content, or transferring data at scale. For casual browsing or streaming, neither device will feel constrained by its wireless connection.

Beyond Wi-Fi throughput, the two tablets are functionally indistinguishable across this entire spec group. Both run Bluetooth 5.4 and USB 3.2, neither offers cellular, 5G, NFC, GPS, or HDMI output, and both carry the same sensor suite — gyroscope, accelerometer, and compass. Software feature parity is equally complete: split screen, Picture-in-Picture, dark mode, dynamic theming, child lock, multi-user support, on-device machine learning, and the full suite of privacy controls are present on both devices without exception.

Given how thoroughly matched these tablets are across connectivity and software features, the OnePlus Pad 3 claims a narrow but genuine edge purely on the strength of its superior Wi-Fi download ceiling. For most users this distinction will be invisible in daily use, but for those in high-throughput network environments it represents the only meaningful differentiator this category has to offer.

This is as clean a tie as a spec comparison can produce. Both the OnePlus Pad 3 and the Xiaomi Pad 8 use DDR5 memory and both support multithreading — and that is the entirety of the data available in this group. DDR5 is the current-generation memory standard, offering higher bandwidth and greater power efficiency compared to DDR4, and its presence in both devices confirms neither cuts corners on memory architecture.

Multithreading support, meanwhile, means both processors can handle multiple tasks across CPU threads simultaneously — a fundamental capability for smooth multitasking and responsive app performance that is expected at this tier of hardware.

With both specs identical across both products, this category is a complete draw. Neither device holds any advantage here, and prospective buyers should look to other specification groups — particularly Performance and Design — to inform their decision.
